1. Solubility Rules

2. Vocab Soluble Insoluble Precipitate Dissolves in aqueous solutions
Does not dissolve in aqueous solutions
Precipitate
An insoluble substance (s) made during the reaction of two solutions (aq)

3. General Solubility Rules
Use STAAR Chart to determine Which Ionic compounds are soluble (aq) and insoluble (s)

4. How to predict products
Ex.) Na2 SO4(aq) + BaCl2(aq)  ? 1. Switch the two metals Na2 SO4(aq) + BaCl2(aq)  NaCl + BaSO4 2. Check the charges Na1+ Cl1- + Ba2+ SO Balance the equation Na2 SO4(aq) + BaCl2(aq)  2NaCl + BaSO4 4. Check for solubility Na2 SO4(aq) + BaCl2(aq)  2NaCl(aq) + BaSO4(s)
